摘要： A transmitter apparatus wherein a relatively simple structure is used to suppress burst errors without changing the block sizes of encoded blocks even when the number of modulation multi-values is increased. An encoding part subjects transport data to a block encoding process to form block encoded data. A modulating part modulates the block encoded data to form data symbols; and an arranging (interleaving) part arranges (interleaves) the block encoded data in such a manner that the intra-block encoded data of the encoded blocks, which include their respective single different data symbol, get together, and then supplies the arranged (interleaved) block encoded data to the modulating part. In this way, there can be provided a transmitter apparatus wherein a relatively simple structure is used to suppress burst errors without changing the block sizes of encoded blocks even when the number of modulation multi-values is increased.

摘要： According to one embodiment, a module comprises a connector into which a first plug and a second plug are insertable. The connector includes a housing and a terminal portion provided in the housing. The housing includes an insertion opening part which exposes the terminal portion outside, a back part positioned at an end part opposite to the insertion opening part in the housing, and a side part provided between the insertion opening part and the back part and configured to oppose to the plug when the plug is inserted into the connector. The side part includes an inclined part which continues to the insertion opening part and is inclined such that a distance between the inclined part and the plug increases in a direction from the back part toward the insertion opening part to form a gap between the inclined part and the plug.

摘要： Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

摘要： Channel fluctuation values on propagation paths of modulated signals transmitted from a plurality of antennas are estimated, an eigenvalue of a channel fluctuation matrix created with the above-mentioned channel fluctuation values as elements is found in order to relate antenna received signals to modulated signals, and using that eigenvalue, receiving antenna selection, combining of modulated signals, and weighting processing on soft decision decoded values, are performed, and modulated signals are demodulated. By this means, it is possible to perform demodulation processing based on the effective reception power of a modulated signal (that is to say, the essential reception power, of the reception power obtained by a receiving apparatus, that can be effectively used when demodulating a modulated signal), enabling the precision of demodulation of modulated signals to be improved.

摘要： An encoding device and decoding device for improving an error floor while taking advantage of the features of a convolutional code capable of encoding/decoding an information sequence with an arbitrary length are disclosed. An error correction encoding section (110) is provided with an LDPC-CC encoder (111) and an LDPC-BC encoder (112). The LDPC-CC encoder (111) acquires an LDPC-CC code word sequence by applying LDPC-CC encoding to a transmission information sequence. The LDPC-BC encoder (112) acquires a parity sequence by applying LDPC-BC encoding to the LDPC-CC code word sequence. The LDPC-CC encoder (111) further applies the LDPC-CC encoding to the parity sequence.
